Always draw the back of the head, can not draw the face, LORA can not be used

When I turned on the lora switch, I kept reporting errors: raise ValueError("PEFT backend is required for this method.") My peft.__version__=0.11.1 Transformers. __version__ = 4.41.2
If I don't turn on the lora switch and I turn it on, the result is no face, it's all the back of the head, but there is a face in the skeleton.
